NASA Unveils Jaw-Dropping Close-Up of Bizarre Asteroid: What You Need to Know!

NASA’s Lucy spacecraft recently zoomed by an intriguing asteroid called Donaldjohanson. The images it captured show the asteroid’s unusual double-lobed shape. This asteroid, named after the anthropologist who discovered human ancestor fossils, is a contact binary. This means it was formed when two smaller bodies collided and stuck together, creating a unique structure.

Hal Levison, a planetary scientist and principal investigator for the Lucy mission, noted that Donaldjohanson has "strikingly complicated geology." As scientists study this asteroid, they hope to uncover secrets about how planets in our solar system were formed.

On April 20, Lucy got as close as 600 miles (960 kilometers) to Donaldjohanson, taking pictures every two seconds. This encounter confirmed the asteroid’s contact binary status. Researchers found Donaldjohanson is actually larger than they thought—about 5 miles (8 kilometers) long and 2 miles (3.5 kilometers) wide at its widest point.

Lucy launched three and a half years ago and already flew past its first target, another contact binary called Dinkinesh, in 2021. These initial encounters are warm-ups for the bigger mission: studying Jupiter Trojan asteroids. These unique asteroids are in stable positions within Jupiter’s orbit, influenced by the planet’s gravity. Surprisingly, no spacecraft has ever approached a Jupiter Trojan before.

Tom Statler, a NASA program scientist for the Lucy mission, highlighted the impressive quality of Lucy’s early images. He believes this could greatly enhance our understanding of solar system history.

In the coming weeks, the data from Lucy’s various imaging tools will be processed and analyzed. For now, the spacecraft will travel through the main asteroid belt, gathering more information. Lucy is set to encounter its first Jupiter Trojan, Eurybates, in August 2027, with more encounters planned until 2033.

In a recent NASA survey, over 80% of Americans expressed excitement about discovering new information about our solar system. These findings illustrate how space exploration sparks curiosity and admiration, not just for scientists but for people everywhere.
